The two approaches for calculating the measurable

Conclusions
In this paper, we have reported a facile one-spot chemical GF 109203X method for the preparation of self-assembled water soluble MnO2 nano-composites on a tubular secretion large scale involving no templates at room temperature. The CTAB plays important roles in regulating the structure features, and hence morphology of the resulting MnO2 clusters. The morphology has been changed in the presence of shape-directing CTAB which leads to the formation of nano-wires and/or lamellar nano-sheets and requires no precise equipment.
